In this embodiment, the through outlet 302 is preferably a through outlet communicated with the inlet 301; the vertical discharge hole 303 is preferably a discharge hole vertical to the feed hole 301; when the material is required to be conveyed directly, the feed port 301 is communicated to the direct feed port 302 through the valve core direct pipe 503, as shown in fig. 1; when the included angle of the material conveying pipeline needs to be switched to 90 degrees, the feed port 301 is communicated to the vertical discharge port 303 through the valve core baffle 505, as shown in fig. 3; the switching between the two states can be realized only by driving the valve core 5 to move up and down through the piston rod 101 of the hexagonal non-rotating cylinder 1.

As shown in fig. 1 to 5, in this embodiment, the spool baffle 505 is an inclined baffle, and the inclined baffle is obliquely connected to the vertical discharge port 303 from the feed port 301; the valve core straight-through pipe 503 is parallel to the direction between the feed inlet 301 and the straight-through discharge outlet 302. As shown in fig. 1 and fig. 3, the valve body 3 of this embodiment includes a limit pin 304, the limit pin 304 is disposed at an inner side of the valve body 3 close to the feed port 301, and is disposed below the feed port 301, for limiting the valve element through pipe 503, and correspondingly, a limit pin notch 305 for accommodating the limit pin 304 is disposed at a side of the valve element baffle 505 close to the feed port 301, so as to facilitate the implementation of the position limiting function of the limit pin 304.

As shown in fig. 1 and fig. 3, in this embodiment, the limiting pin 304 is further disposed at the inner side of the valve body 3 close to the through outlet 302 and below the through outlet 302, so as to further ensure the stability of the position-limiting function.

As shown in fig. 3, the present embodiment further includes a spool flange 4, and the piston rod 101 of the hexagonal non-rotating cylinder 1 is connected to the spool 5 through the spool flange 4, so that the connection between the hexagonal non-rotating cylinder 1 and the spool 5 is more stable and reliable.

As shown in fig. 1 to 5, the valve element 5 of this embodiment further includes a guide post 504, a movable top ring 502 and a deformable rubber ring 501, the valve element through pipe 503 is connected to the valve element baffle 505 through the guide post 504, the movable top ring 502 is sleeved on the guide post 504, the inner diameter of the movable top ring 502 is slightly larger than the outer diameter of the guide post 504, and the movable top ring moves between an upper limit member and a lower limit member of the guide post 504; the deformable rubber ring 501 is arranged between the movable top ring 502 and the valve core through pipe 503, and the deformable rubber ring 501 is arranged on the guide column 504.

As shown in fig. 1, when the feed inlet 301 is communicated to the straight-through discharge outlet 302 through the valve core straight-through pipe 503, the materials are fed in a straight-through manner; as shown in fig. 3, when the feed port 301 is communicated to the vertical discharge port 303 through the valve core baffle 505, materials are vertically fed, and the included angle of the material conveying pipeline is 90 degrees.

More specifically, as shown in fig. 1, when the material needs to flow from the feeding hole 301 of the valve body 3 to the through discharging hole 302 of the valve body 3, the piston rod 101 of the hexagonal nonrotating cylinder 1 deactuates the valve core 5 to the position shown in fig. 2, at this time, the piston rod 101 of the hexagonal nonrotating cylinder 1 acts on the valve core 5, the movable top ring 502 is limited by the limit pin 304 of the valve body 3 and then moves upward along the guide post 504 of the valve core 5, the movable top ring 502 presses against the deformable rubber ring 501, and the deformable rubber ring 501 deforms and expands to fill the gap between the valve core 5 and the valve body 3, so as to form a seal. The magnetic switch 6 on the hexagonal non-rotating cylinder 1 senses the material to be in place, and the material begins to flow. The material enters the valve body 3 from the feed inlet 301, flows through the valve core 5, and flows to the through discharge outlet 302 of the valve body 3 through the core of the valve core through pipe 503.

As shown in fig. 3, when the material needs to flow from the feeding hole 301 of the valve body 3 to the vertical discharging hole 303 of the valve body 3, the piston rod 101 of the hexagonal non-rotating cylinder 1 drives the valve core 5 to return to the position shown in fig. 3, the magnetic switch 6 of the hexagonal non-rotating cylinder 1 senses the position, and the material starts to flow. The material enters the valve body 3 from the feed inlet 301, flows through the valve core 5, and is reversed by the valve core baffle 505 to flow to the vertical discharge port 303 of the valve body 3.

The example of pushing the valve core 5 to move is that the hexagonal non-rotating cylinder 1; the hexagonal non-rotating cylinder 1 acts on the valve core 5 to transmit force to the movable top ring 502, the movable top ring 502 moves along the guide column 504 of the valve core 5 after being limited by the limiting pin of the valve body 3, the movable top ring 502 presses the deformable rubber ring 501, and the deformable rubber ring 501 deforms and expands to fill a gap between the valve core 5 and the valve body 3, so that the sealing requirement is met.

In conclusion, the valve body 3 and the valve core 5 are specially designed, so that the included angle of the material conveying pipeline can be switched to 90 degrees, the structure is simple, the processing and manufacturing are more convenient, the cost is low, and the construction difficulty is low; on the basis, the special design of the valve core 5 can meet the sealing requirement of the material conveying pipeline on the basis of low cost, and the reversing requirement of large-scale production of the material conveying pipeline is met.
